Measurement Limits

The protection circuitry of the multimeter can prevent damage to the instrument and protect against the danger of electric shock, when the Measurement Limits are not exceeded. To ensure safe operation of the instrument, do not exceed the Measurement Limits shown on the front panel, it is defined as follows:

The user-replaceable 10 A current-protection fuse is on the front panel. To maintain protection, replace fuse only with fuse of the specified type and rating. About the specified type and rating of the fuse, please refer to "7 Current Terminal Fuse" in "Front panel overview" on page 7.

Main Input Terminals (HI Input and LO Input) Measurement Limits The HI and LO input terminals are used for voltage, resistance, continuity, frequency (period), capacitance, diode, and temperature test measurements. Two Measurement Limits are defined for these terminals:

HI Input to LO Input Measurement Limit

The Measurement Limit from HI Input to LO Input is 1000 VDC or 750 VAC, which is also the maximum voltage measurement. This limit can also be expressed as 1000 Vpk maximum.

LO Input to Ground Measurement Limit

The LO input terminal can safely "float" a maximum of 500 Vpk relative to ground, where ground is defined as the Protective Earth Conductor in the AC mains power cord connected to the instrument.

As implied by the above limits, the Measurement Limit for the HI input terminal is a maximum of 1500 Vpk relative to ground when LO Input is at its maximum of 500 Vpk relative to ground.

Current Input Terminal (I) Measurement Limits The Measurement Limit from the current input terminal (I) to the LO Input terminal is 10 A (DC or AC). Note that the current input terminals will always be at approximately the

1.General Safety Requirements

4

same voltage as the LO Input terminal, unless a current protection fuse is open.

Sense Terminals (HI Sense and LO Sense) Measurement Limits The HI and LO sense terminals are used for four-wire resistance measurements. The Measurement Limit from HI Sense to LO Input is 200 Vpk. The Measurement Limit from HI Sense to LO Sense is 200 Vpk. The Measurement Limit from LO Sense to LO Input is 2 Vpk. Note: The 200 Vpk limit on the sense terminals is the Measurement Limit. Operational voltages in resistance measurements are much lower – up to ± 12 V in normal operation.

Measurement Category

The safety rating of the multimeter: 1000 V, CAT I IEC Measurement Category I. The maximum measurable voltage is 1000 Vpk in the HI -LO terminal. 600 V, CAT II IEC Measurement Category II. Inputs may be connected to AC mains power (up to 600 VAC) under Category II overvoltage conditions.

Measurement category definition

Measurement CAT I applies to measurements performed on circuits not directly connected to the AC mains. Examples are measurements on circuits not derived from the AC mains and specially protected (internal) mains- derived circuits. Measurement CAT II applies to protect against transients from energy-consuming equipment supplied from the fixed installation, such as TVs, PCs, portable tools, and other household circuits. Measurement CAT III applies to protect against transients in equipment in fixed equipment installations, such as distribution panels, feeders and short branch circuits, and lighting systems in large buildings. Measurement CAT IV applies to measurements performed at the source of the low- voltage installation. Examples are electricity meters and measurements on primary over current protection devices and ripple control units.
